I think the way it works is that it's fine to, say, post up a new thread in response to something somebody's said in another as long as a mod doesn't decide that it's being done purely to get at a particular poster for personal reasons.
Thatnks, I'm not sure that's true though. It seems that the rule is based on if the OP mentions another poster. I suppose we can experiment and see what gets binned.
If anybody wants to do a call-out on me for any reason, just PM what you want to say and where you want to say it and I'll post it up for you. I'm pretty sure you can't do a call out on yourself.
