Quite a few rink websites around here have up to date skating session schedules on-line, which is the most important thing, IMHO.
Most give address and phone number. Many give driving directions (which is great).
Some list the names of the skating clubs (hockey, figure, speed, curling, etc.) that skate there, including contact info, and list available facilities (e.g., pro shop, snack bar, room rentals), and the rink size. If you are an indoor rink, say so. Many list FAX numbers. Some list pro policies. E.g., "any visiting coaches with PSA, ISI or USFSA insurance can teach after we verify you".
For heavens sake, say "Ice Rink" or "Ice Arena" on the home page, so no one wonders if you are a roller rink.
If you run a forum or mailing list, you have to censor it, to keep it decent, legal and avoid advertising commercial products and your competitors, which must be a lot of work.
I think commercial websites should be simple enough that any browser or mobile device or Google TV, etc., can easily read it, regardless of screen size or data rate. You need all the customers you can get. Simple unscripted HTML only, with maybe a low byte count facility image.
Register your page with at least the Yahoo and Google search engines.
If your rink belongs to ISI or USFSA, make sure they have your web address.
