Nice to find your post here.
Regarding posting, IV doesn't use a markup language to post links and charts like CS and most blogs do. Instead it uses Rich Text. It's actually a little easier and offers more flexibility.
Start with enabling Rich Text in your Preferences. This provides a Word-like tool bar that provides familiar features.
Post links by clicking on the "chain" icon above and simply filling in the blanks. It produces a hyperlink like this Example :)
Posting charts and images is easier with Rich Text because you simply copy and paste them in. No uploading them to a third-party storage site.
Anyway, try them out. Looking forward to you being able to post some charts!
