lol, that was me that told Gold Finger how to do the signature link. Since I was about to comment on the snails, I'll chime in with that, too!
Like he said, just type what you want to say, then highlight the text, click the insert link icon, and type the link in the popup.
As for the snails, I have pond snails and mts. I really thought the pond snails would be mostly removed when I switched to sand, but they've already started coming back (and I definitely don't overfeed). But the one trumpet I have in the sand tank, and the two I have in the other tank, haven't had any visible babies yet, so I think they might breed more slowly? Either way, I love the mts. I think they're really cool looking, when I do see them. My LFS thought I was crazy when I asked for some, until I said planted tank, then he said, "Oh! These are exactly what you want, then. They're perfect for that."
So, maybe not very helpful, since I don't know if you really *need* them, but I do enjoy mine so I thought I'd throw that out there.
