tags contenttypeid?

[al3bed]

hello

I want to use vbulletin tags in add-on but there is something I can't understand yet, it is in database Table: tagcontent field contenttypeid ..

I notice that if it's blog tag id is 15
and id become 2 if it's a thread tag

so if I want to insert tag for another content type of my own programming I know what I will put in each field in table tagcontent and table tag except for contenttypeid field .. is it right to put specific id rather than 15 and 2

thanks for your attention
