HI,
Firstly sorry if we have not answering your questions as yet, we do answer every question as soon as we can, and will be getting to yours asap too
As for the bold issue, if you type your text normally then highlight the part you want in bold then click the "B" button, you should get the [B/] around the part you highlighted..
this works the same for italic or underline etc.
if you select "preview post" before "submit reply" you can see how your message will look before its send..
i hope this clears things up for you..
