I take it you just want to delete certain lines which are particular links.

There are two basic options.

1) Just delete those lines.

2) Just comment out those lines - this leaves the content there without erasing it.

This opinion is based on reading the served page in the 'View - Page Source' link in the menu bar (Firefox).

If the page is being assembled by the server from 'bits', you can have any sort of mess to wade through - which is why I still prefer the old fashioned HTML way ... :-)

Read your 'contract' carefully - if they have been clever in setting up their - ok the phrase 'extortion racket' may be legally incorrect if you agreed to the terms - you may not be allowed to edit the content (particularly removing any) yourself. You may find that they can pull the site from the hoster if you 'muck with it'. Which is why 2) may be the best way for a start ... :-)
