Welcome to the forums.
1st: How do you check your mail in forums?
Two ways, either click on My Home, then on your Inbox, or just click on the flashing envelope - these are both to the right of where it says Welcome ilovepasta12
2nd: How do you send mail in forums?
Two ways, either click on My Home and Send A Message, or click on the name of the person you want to send a message to, then click the 'Send Message' link.
3rd: What is forums? Is it like a chat place?
Not so much a chat, more a message board. In chat you will get instant answers, here it could be instant, it could be a day or two, but normally within hours. Read some threads and you will get the idea of how we operate here.
4th: What is: Make post using UBBCode -or- withour UBBCode/HTML ??
You can only use UBB code in the forums. I have used it to make your question italic. You can either type in the code yourself or use the instant code as in question 5. To type in the code you must put an opening code and a closing code. The codes are within square brackets. [b ] without the space after the 'b' is the opening code for bold, the closing code is [/b ], again without the space. There are a number of functions, bold, italics, colours, links, quotes etc. Look in FAQs for a complete list of available codes.
5th: What is: Instant UBB Code??
I don't think we have the option of that here. That would be where you have a 'box' for a quote, image, link etc and enter the text within the box and the codes will be placed for you.
