Thanks for your reply.
Nah I haven't fallen out with the other forum, but figured I may as well use all the resources at my disposal.
The reason I asked about part time is because I would only be available on weekends (I have a full time day job) so wasn't sure if employers would be uninterested in hiring a weekend person or not. I don't particularly want to spend the money on the rating only to find that no employers are remotely interested in employing someone part-time.
I haven't taken many pax up yet (most of my friends are too poor and/or find the idea terrifying) but those I have taken up said I explained things well and they felt very safe with me etc, so I suppose that's a step in the right direction. I just feel that there's probably a gap between 'explaining things well' in that situation and actually teaching somebody. I really don't want to be 'that' instructor, who is a crap teacher so really shouldn't be instructing...
