When i run the nearforum and add a post, if I don't set the tags, the exception is throw:
The TopicTags column of Topics table has not nullable column.
The exception can be resolved ?

System.Data.SqlClient.SqlException was unhandled by user code
Message=Impossible d'insérer la valeur NULL dans la colonne 'TopicTags', table 'Forums.dbo.Topics'. Cette colonne n'accepte pas les valeurs NULL. Échec de INSERT.

Im not getting that expection when I try and post a new thread without tags.

I just get a message just above the Subject , telling me that i need tags.

On current version in source code there are a comment on RequireField that cause this bug.
Look in Topic.cs in NearForums project.
        [RegexFormat(@"^\s*([\w\-\.]+(\s+|$)){1,6}$", RegexOptions.IgnoreCase)]
        public TagList Tags

What did you type in the Tag field, to get the error message?
  1. If you just let tag field be empty when posting a new thread you will get an intentionally fail msg just above the subject field.
  2. RegexFormat just tells that:
^ = Begin String
\s* = Start of string can contain numerous amounts of space


\w = Literal or digit or underscore
\- = 
\. = Any character


\s+ = One or more space
|$ = Or end of string

{1,6} = Min and Max amounts of tags for each post
$ = End of String

With empty value in Tag field,
The bug is that I don't have the msg above the subject field, I have only the exception on full screen.
On 733 revision the RequireField attribute has been commented, and is the cause of this exception.
If I uncomment this attribute, I have not the exception.
I have make two test and look the different result

WITHOUT RequiredField:
WITH RequireField :

Actually on 734 revision this line is commented and produce this bug.
I think,

The regex accept spaces but not empty Line. You should try Update the jquery scripts. Are you using visual studio.?

Sorry but the client validation is not enable on this form when I'am test, I have test on http://forum.darkshiftstudios.com/news/ too and the client validation is not activate, so the Jquery version does not affect the good or bad behavior,
I use viusal studio 2013.

Its because i've not removed RequiredField attribute. It still stands as //RequiredField in Topic.cs

Have you looked into the TinyMCE feature?
Maybe I could add you on skype or some other social media, so that we can share information about nearforums?
