Dammit. I just typed for 5 minutes then accidentally hit my back button on the mouse and it's all gone. LOL!
I'll start again.
OK Deb ... the Columnists category are for regularly self-published columns (opinion and editorial... op ed). LR writes and published his 2x a week, usually with a socio-political theme, offering his opinions. Michael Bonanno writes about similar themes, offering his opinions, and publishes them here on a regular basis. Cecil publishes his Sunday Stream once a week on Sunday, examining spiritual and philosophical themes, offering his editorial opinions. (BTW, we'd really like to have more columnists, especially some who have contrary political leanings to LR and Michael because we don't want to appear to be advocating any one agenda even tho LR says Michael makes LR look like a moderate.

)
The Studios, yeah, you're right... they've (up until now) been forums where the moderating members discuss various different topics which they are particularly interested in.
Perhaps these new Studios need a new category and shouldn't be in the Studio section as you suggest, but they're definitely not columns. We just thought some of you might want a spot to archive your own writings. I hesitate to call them BLOGS because I don't really like that name, but essentially that's what they'll be. They can add poetry, rants, essays, stories, journal or anything else they want.
Hmm... Ya got me thinking. Originally in the site plan, I had planned for a section called "Artlogs" (click HOME at the top and you'll see the plan for the main site which we've barely developed yet).
Maybe we should create a new category called "Artlogs" for judih's and stilltrucking's spots and other members who might want one.
What do you think?
