Gemma,
Have you considered adding a Bali section to this site? I have recently joined a Bali travel forum that has a lot of disgruntled users because of the way the site is over moderated. I thought if you could include a Bali thread here it would not only increase traffic a great deal, leading more people to Lombok, but also perhaps give you another area of revenue through advertising.
I would also be prepared to get involved in a little sculduggery and let all disgruntled users on the other forum, and there are many, know what else is available.
I hope you don't find this suggestion offensive as I am certainly not trying to tell you how to run your site. I, and others, are simply looking for other options but are up to this point are unable to find anything appropriate.
Your humble member
