I don't know all the ins and outs of here even though I have been hanging around for years haha but I can't see a problem with that - people put links from youtube, google, all sorts of pages for challenge inspiration and ideas.
If you look at the T&Cs, there's a part on discussion boards that states:
"We reserve the right to remove any content deemed to be for commercial purposes.... not of interest to the general community... [or] inappropriate for general consumption."
I've seen lots of links posted, and have posted some myself, without any issues. I suspect as long as you meet the criteria above, you should be fine.
@annied@lsquared Thank you both for your replies. I am confused because when I try to format my URL using the formula in "How Can I Format My Reply?," everything below my link disappears. I was wondering if that's because it was Pinterest or something? I posted the URL but it's not a link. I guess people can copy and paste it if they are interested.
