I take breaks too Artb, I go away for about a week and then come back. It's healthy to do that so we don't get too involved. Some people don't post on the Weekends, others just post every once in awhile.
It's better to have a Mod approach you with this than to down right throw you out without a reason. So this is a good thing.
Give yourself some time to breathe and when you do come back to post, love the people that your posting to. Put faces to them as if they are standing in front of you and your words will reflect that in your post.
When a thread starts to get heated, pull away immediately and ignore the thread. Better to be on the right side with peace than to be on the wrong side with strife. There is nothing wrong in being silent especially if someone is speaking against you and you want to defend yourself. It's a temptation to do that, so try not to give into it. Walk away from it and let those that remain who have no sense to learn fight among themselves.
