First, I'll post some text which is italicized but not bolded:
This text is italicized but not bolded.
Does it appear bolded to you?
Yes.
Second, you should post a snippet of the text that appears bolded to you when you've only applied italic tags, and wait to see how it looks to other readers.
I'm assuming you mean I should create something in this thread, as I did in the other, and see what the results are. Will do.
