Are you aware of any similar messageboards to Sydenham Town Forum and SE23.com for discussion relating to either of the following areas:

Lewisham
Catford
Deptford
New Cross
Ladywell
Southend
Downham
Grove Park
Lee
?

Bromley
Orpington
Chislehurst
Farnborough
Cray
Penge
Anerley
Beckenham
?

What about anywhere in the Sevenoaks district?

I just realised that Virtual Norwood covers Penge and Anerley as well, but what about the other areas?

http://www.eastdulwichforum.co.uk/ covers SE22. Don't know about the areas you listed.

There is hithergreen.org.uk which also covers Lewisham and bits of Catford and Ladywell.

Brockley Central mainly covers the Hill Fields side and includes Ladywell and New Cross

There's also the The Hill which is the Telegraph Hill side of Brockley and includes New Cross

There is Downham Online for that area but tends to be full of ole' codgers talking about the 1950's.

Thanks mate, but how do I get to the forum on that Bromley site you linked? I joined Downham the other day...
