In reply to Ian Parnell:
I'll second Mr Parnell on this one. Having a little experience from both sides of the coin (submitting photos to various mags and editing Summit), I haven't come across any vast hidden pool of talent out there. Well, not yet anyway...
In the case of Summit, we do send out a photographers mailing list to around 100 photographers prior to each issue. And whilst it does throw up the occasional nice surprise, most of the photos are donated (for free) from the more established photographers. It's no surprise really since they have a bigger collection, use higher quality equipment, so odds are, for any given wants list, they will send more in. If you'd like to join the mailing list by the way, email summit@thebmc.co.uk.
Likewise, Summit is also a good way of getting published, if you want to. Lots of people from these forums have had articles published in Summit. There is, for example, a "last thoughts" page. 800 words, a rant on any subject - there surely must be some contenders for that! Yes, you don't get paid. But often, if you're trying to get photos and words published to start with, you won't. As Ian says, a lot of the writing that comes in has to be heavily edited. But that's to be expected I guess. The professional writers are off writing professionally, not beating down the doors of the BMC.
Send anything in to summit@thebmc.co.uk. We can't guarantee to reply to every submission. I don't think any magazine realistically can, but will get back to you if it's of interest.
Finally I think in general people (myself included) tend to have too much attachment to their own photos and words. The harsh reality is that often they're not very good, especially since we're all bombarded with very high standard writing and images in the non-climbing media every day. Get other people to give them the once over before sending them in.
Cheers.
PS. As well as scouring the land for free content to suck into Summit, I also take photos for Climb. So if you fancy writing a UK rock article on any area, and would like to team up then give me a shout.
