@kiwibritMay 17.2010 — #This is not an HTML matter, the job needs to be done server-side, using something like php or asp.net (you could probably also use javascript, but I would not recommend it for this purpose). If you have no preference, fins out what your web host supports, and learn and use that - and ask questions in the appropriate part of the forum.
@PETTEMay 17.2010 — #Look into PHP, Javascript won't help either. Anything client-side won't help. Most hosts support PHP. The area you're after is the mail () function, very easy to use if you're exprienced.
