I moderate over 100 communities and all of them have 2 things in common:
1) I allow for the usage of tags in my comms.
2) Every single one has a tag for 'iconnage'.
Most from an icon dump at Weirdfolks, which has the most iconnage posts of all my comms.
This may or may not work but I figured I wanted to try an icon community. You may post your icons here or post a few with a link back to wherever you have the rest of that particular set. Any and all kinds of icons are allowed here. You should use LJ·cuts at your own discretion but it's not a big deal here. As most icons are only about 100x100, or less, you could do a post with 7 rows of of 5 icons and it still wouldn't be that big. Anything more than that, go with an LJ·cut...
...but regardless, keep a little space between each icon. Unless you know the HTML to do tables, which I don't, it keeps them from stretching wider than the screen.
Other than the aforementioned linking, do not advertise your communities here! If you want to advertise them then do so at We·Need·a·Life. I used to allow advertising in any of my communities if it kept to the theme of that community but I'd like to cut down on that a bit...until it dwindles to nothing.
