i do not like that people change the subject of threads... would like the inital subject to be kept

is there a way to do that?
thanks

It would probably suffice to remove the subject input field from the appropriate templates. A complication is that the same templates might be used for initial posts and replies, so some conditional logic would be necessary in the scripts that use the templates.

Another approach would be to simply avoid updating the subject in the database when a reply is made, but that might confuse your users ("I changed the subject, why didn't it work?").

Thanks
It is annoying when people change the subject of the messages, but fortunately not too many people do.

Probably best to change it in newreply.tmpl to a hidden field. I think if you just remove it, addpost would complain that the field was empty.

Maybe the same for editpost if you weren't an admin or a mod, make it a hidden field so it can't be changed.
