Just so you know you can edit your posts. If you add a new item to your shop you can edit the OP with the new items. It helps keep your thread from getting cluttered up and also help people know exactly what you're selling without having to scroll all the way through the thread.
thing is- it still get burried underneath all the other forum threads I kinda think its a bit better than just putting "bump" all the time <~>
You don't have to write jist "bump". You can write anything in the post. I was more referring to keeping your OP updated so its easy to see what items you sell. Also, just incase you weren't aware, as per forum rules, you can only bump a thread 3 hours since the last post on it.
