Isn't that the purpose of the "public" board? Seems to me that if you start doing all this in chat, there might as well not be a board, and there is no archive available to look things up, refer back to.
Agreed. Having the forums where help is given is very important and should be encouraged. As far as tech help in chat there is no going back to see what step you may have missed and there is nothing left to help the next member that has the same issue.
