I have used SO since they opened. These days, at least half of my questions get closed as off topic or marked as duplicate - and I always do a lot of research first - but sometimes I just do not know the right keyword to search for - or do not understand the deeply obscure limitations to what is considered on or off topic... I will ask my question, hope to get an answer before it is closed.
