Hello all
I am using a WYSWYG editor in my wordpress forum.
Now the problem is that when i am saving the content some of the tags in the content like underline and bullets,color are striping in the data.

I am not getting how to allow these tags.

Any Immidiete help will be appricieted.
I am using Tinymce ,if you any other editor suggestions then please give that also

Thanks & Regards
