Welcome on board.
We don't have such a place to introduce yourself. On other forums I have been on where there is such a place no one reads them anyway. There tends to be two sorts of users here. The ones that answer questions all the time and very rarely pose them, and those that ask, get answers and are off. There are much less members that do both.
Anyway however you decide to use this you are welcome.
Make sure you read the "How to use this forum" sticky post, it is the same for each section and it warns you against doing annoying things that you could do. Anyway if you do transgress some one is bound to tell you so don't take it to heart we are really a friendly bunch here. Remember there is no question stupid questions, just stupid ways to ask them.
