The questioner merely needs to specify what they are using and the appropriate response will be made.
I disagree with this, it goes against the basic principle of web design i.e. treat all users as first time users. This is the first thing any professional developer would know.
To include an option list creates several problems:
a. users have to wade through each posting to determine which postings relate to asp.net and which don't (time consuming, and requires more effor from the user).
b. Including an option list means additional targeted coding (the options list itself, specifying the language being used on the message index, and filtering), which in a standard forum like this, the site owners may not have access to/control over.
c. much easier to simply to set up a separate forum with no code alterations.
d. as ASP.NET is definately going to grow in popularity, mixing the forums creates headaches for everyone in the long run.
e. more convienient for all
As for the c# thing, how many people here use it?
Well as you can only code ASP.NET in C#, VB.NET, or JScript.Net (not recommended), I'm surprised you made that comment.
I'd be interested in a response by the site owners.
