There was a bug whereby members could not submit web links. That's now fixed, so go ahead and submit whatever you think is appropriate.
You can submit links to any of the categories listed under Main Menu>Links. If there isn't an appropriate category, put it in miscellaneous. I'll create new categories and move links from here when there's a need. Note that your submitted link will not show until I've approved it. Approval will not normally be witheld!
To submit a link, log-in and click User Menu>Submit Web Link. Fill in the form, submit and you're done!
