Hi,
i am new to the list and wonder if i can ask some PHP question here: if i fail the meaning of this list pls just ignore. thanks for answer anyhow ;)
NEWSLETTER : i couldnt find a function like this in mediawiki and did not find an extension, too. during searching for extentions i decided to write a simple extension to mail a newsletter to registered users (only some dozend) but failed as i am not so trained with php
must mention that the newsletter function already worked fine when i separated the newslettersend-module and used the (a little modified)original emailform of specialpages to try it. but i wanted a special entry in specialpages as NEWSLETTER and now mixed something up. --the mailform appears but when i "submit" it complains class double-defined and i cant find out where --i also want to separate the db-connection as this seems to be a little unsecure ;) (how?)
best regards Arno
