is there an easier way of pinging groups since it's not working?

Nope. Depending on the group you're looking to ping, you might be able to individually ping all the members, but I wouldn't reccommend it unless it's a personal group of yours, or a friends/cult group or something (it'll also be kind of a pain). In place of buysellcw, I've been using bwcw and omfgpurple, since both of those are working and I'm looking to buy/sell items that fit in the categories. I tried omfgteal earlier but the ping never came through (at least for me)

ok thanks, and also is there a way to edit a post to add the ping friends feature since i was too stupid to not use that in the first place?

I don't think so, you could always edit in a ping to ask a friend or two if they could post, and then ping friends in your next post

yeah, that's what i'm thinking of doing thanks!
