Not unless it was a whole sub-board. Thread titles need to describe the nature of the help, in order that they catch people's attention better in the unread posts list.
Otherwise you just end up ignoring new posts on the "help wanted" thread, because the last n posts have been about someone wanting to borrow a trailer in East London, not realising the latest post is from a Mancunian in dire need of some help with their knackered headset.
(People who navigate the board hierarchically won't have this issue, but conversely, you'll have to wait for them to specifically check the help wanted thread.)
