Hi Mike
Here are some suggestions for sub-forums (just a few). Yourself and others may have different ideas, these are just mine 'cos I like a bit of structure (old-fashioned I'm afraid

)
In the Van Conversion section, sub-forums might include:
- My Conversion Project
Purpose would be for folks to display photos and record the progress of their own conversions)
- Wanted and For sale
A classified section (anything from accelerator cable to Z clips
- Habitation Electrics
- Habitation Gas and Plumbing
- Habitation Furnishings and accessories
Purpose would be for folks to post hints, tips, ideas, questions, problems etc
- Guides and how to ...
How to fix...
- Mechanical advice
Self explanatory
In the Living and Travelling in a Van section, subs might include
- Out and about in my van
Folks could post their ongoing trips
- Wildcamping Locations
For posting information about places they stop over
- Campsite reviews
In the common room, subs might include..
- new members section
For new members to introduce themselves
- members vans
For members to post photos of their vans
- Insurance and breakdown deals
Mike - it is your forum and these are just suggestions for the throwing out!
