You'd have to know how to download/upload images. And you've got to be willing to put in the time to find images; sometimes it can take a while to sift through all of the vaguely labeled images on Flickr. More importantly, all images would have to be licensed under Creative Commons or otherwise be free to use. That means no swiping images from wherever you might happen to find them. No copyright infringement allowed. (I know I've still got quite a few examples of infringement on here but I've already got too much to deal with to go back and update/change/remove them. I plan to eventually!)
I wouldn't feel comfortable bringing anyone on board unless I knew they were competent writers and that they knew their way around the internet. You don't have to be a scholar but you'd have to be able to write something decent and make use of your spell/grammar checker if necessary. As mentioned above, you'd also have to know how to download/upload images. And you'd have to know how to handle Blogger and make nice looking posts with correctly functioning links. You don't have to be a blogger necessarily but it would go a long way toward proving to me that you know how to handle the Blogger site. That said, as far as I know, Blogger is the simplest blogging format so if you know how to post text, links and images on a message board you'd probably be just fine. Still, if you want to contribute I'd need some link(s) to show me that you could do a decent job. It could be a link to your personal site or blog, a message board you frequent, your Facebook, etc., just as long as it includes some proof that you could handle things. If you'd prefer you could just send me an email with some links and pictures to show you know how to do those things and that would be fine.
3. Understanding of or Interest in Paganism/Mythology
You wouldn't necessarily have to be pagan to contribute here but it would help if you have a general knowledge of paganism, mythology and the related symbolism. Or you've got to have a high level of interest in these things and a willingness to spend time learning about them so you could present coherent and interesting posts. There's plenty of things I've posted about that I wasn't very familiar with so I had to spend time learning about them; it's part of the fun!
4. Regular and worthwhile posts
This is pretty self-explanatory. You would be expected to publish at least one post per month (but would be very welcome to publish as many as you wish!). And while long explanations aren't required for each post you would be expected to post more than just a photo and a link most of the time. (I've been guilty of doing this, especially lately, which is why I'm looking for some help! My hope is that with others contributing there would be plenty of time to devote to writing quality posts.)
For the record: I'd still be contributing and have veto power and all that. For instance, if you repeatedly steal images, don't write enough posts or start being a jerk I'd kick you right to the curb. (If life got in the way and you couldn't post for a while that would be fine as long as you gave me some heads up.) I'll also maintain control over reader submissions and the associated email address.
To conclude, if you're not sure what being a contributor would entail just go back and read some older posts and that should give you a pretty good idea. If you have questions before throwing your hat in the ring feel free to ask either through comments or through email at firstname.lastname@example.org. I'd really like to keep this blog going and would greatly appreciate some help. I look forward to working with you on this great project!
