1) Thank you T. Valko for your moral support!
A "change" to the Board current format is certainly undesirable and uncalled for. Besides, "change" doesn't really do justice to the idea!
2) Please let me summarise my suggestion since there appears to be some confusion.
Since the Board requires a "Title" to a "New Thread" to be entered, then why not expanding the requirement to include checking the 1st word of the "Title" against a list of Keywords ??
(The list of keywords may include: Worksheets:, Formulas:, Charts:, VBA:, Pivots:, UserForms:, Dates:, Advanced:, Misc.:)
Is that too much for the board software experts ?? (who're by the way doing fabulous job for free, which is greatly appreciated and acknowledged)
It might well be, I don't have a clue!
3) Existing Threads would remain unchanged, while a New Thread (say, effective 01/01/2012) would have its Title starts with a Keyword.
(By the way, having a Thread marked as SOLVED is an excellent idea, but it is for another user to suggest)
4) If forcing the OPs to select a Keyword from a dropdown list requires tremendous effort by the Board to implement & manage, and requiring such specificity in the Title might unnecessarily cause confusion to the users, as some have indicated, then how about just displaying it as a suggestion in the New Thread page ?
Something like:
"Please Select a Keyword from the List on the Left as the 1st Word in the Title Box."
and leave it to the OPs whether they want to provide a specific Title or not!
This appears to be far simpler than for example compiling the current "Smilies" icons to the right of the Message box, and doesn't represent a "change" to the current format. I think!
Regards.
