I won't disagree with your choice, but I would warn you:
Sometimes it is the one who stands his ground that finds peace.

Regardless of where you go, please keep creating; however you choose and whatever you choose.

Live well.

I wholeheartedly agree with you... but I have no ground to stand on here. I'm just a lurker who was thinking of going active. Besides, if people with much more voluminous galleries are leaving, what good will be done by my staying?

That is the point OF staying, isn't it?
;)

Pardon me for being a blockhead (a la Charlie Brown), but I don't understand what you're getting at, I'm afraid.

Well, for starters,
In order to reply, hit the little "reply to this post" button on the bottom left of a comment, otherwise the only way fro anyone to know that you've replied to them is actively check their comments on each individual piece they commented on every few days.
(It's a bit confusing for a UI, but don't worry, you'll get the hang of it)

And second, the size of a gallery is unimportant. As long as you can create art, and are willing to share it, then you are contributing to art as a whole.
If you want to leave, that's ok. But really think about the reasons why you would want to leave.

There's nothing wrong with lurking, and you don't have to have a big gallery to be an artist. You may not see much good in staying, but it's definitely there. Personally, I would be grateful if you took the time to manage updating both sites. I know it's more work, but you'd get out to more people.
And there really are those of us here who would be sad to see you go.

Either way, we'll respect your choice. I just hope you can find the confidence to not be afraid to post something anywhere you would like.
