A couple of quick comments to add -

I believe Wikipedia look down on people trying to submit pages relating to themselves, or indeed trying to edit them. A friend was put in Wiki jail with a temporary ban, for attempting to correct the page about his own music.

Secondly - as Tony Rees says, the 'notability threshold' they use can be quite a high bar to clear. One of the best ways to help to ensure that a new page you may create is accepted by moderators, is if the subject you're intending to write about is already referenced on other pages.

By way of an example - I'm thinking of writing a page on the folklorist Christina Hole, who has no page at present; but if you search Wikipedia for her name, she already appears many times as her writings have been quoted on other pages, focused on the customs she documented and analysed.

If your chosen subject doesn't have that prior presence, in advance of trying to create a page for them there's value in 'seeding' mention of them elsewhere. For example, if I try to write a page for Tony Rose, to help that along I might edit Dolly Collins's page to note her contribution to 'On Banks of Green Willow'. Tony's work with Nic Jones is thankfully already mentioned on Nic's Wiki.

Thirdly, to re-emphasise what Tony Rees and others state - I'm posting to encourage *all* forum users with time and inclination, plus the subject knowledge and tech confidence, to contribute.
