Hi, Mike_J! I regret that, as a recluse and non-driving individual, I do not belong to any self-help groups (apart from PsychCentral, that is). Consequently I am unable to answer your question. Nevertheless, I am able to offer this empty, overly wordy reply, which will bump you back up to the top of the queue.
