I have been on forum before where an individual has added a lot of good info to the site, and then for what ever reason/events, feels like they should just walk away from it all, and the they go back a edit as many posts as possible down to blank pages and cause a loss of a lot of good info over nothing, I would tell anyone here not to post if were their intention of wiping it all out should they feel they have been wronged in some way and leave.If you contribute to a knowledge base and then expect to wipe it away when you are done, I'd rather not have it here. If it ever comes to that and someone asks to have content removed such as general posts and the like, I will not have a problem with that, but tech info is the kind of stuff people need when they need it.
