Too many users expect things for free and grumble when the people who dedicate their time and money to providing the service make some changes so they can generate some revenue to keep the site going. Maybe create a name and shame board for those moaners?
Just went to see what the Skoda Owners Forum offer for paying. They do have a yearly subscription scheme for £12 per annum. For that they chuck in:
FREEDOM - An enhancement which gives you access to all of the present normal registered features plus:

- Exclusive Freedom Talk forum, 99.9% unmoderated.
- Opens up your account to access your own @briskoda.net email account and web interface (Gmail over 2000Mb of storage).
- Advanced notice of our events with priority booking and discounted ticket price.
- First access to our promotions / group buys.
- Access a gowing list of discounters, suggest one we'll investigate it...
- A journal to show of your projects, car related or not.

As you said it's always an option for the future. Why not create a poll to gain some user feedback?
