Fair points Hugh... altho perhaps telling the organisers of the classes that they must email you every 2 weeks to confirm the classes are still running or face getting automatically dropped from the listings, may help.
My point would be that in the forums any news of new classes starting up can soon sink out of sight for allbeit the most determined of forum browser to find. A lot of people casually passing through this site looking for new classes/dance nights will stop at the main page and take the information from there. Which is great for the established teachers and established nights that already have plenty of custom and so may need the exposure less but hardly encourages new nights and venues which need time to grow so that eventually social dancing times with the venue owners can be neogtiated and extended.
Also there is a lot to be said for the one hour class in the local fitness/social centre for example that would not get a listing on the front page, these classes can be more local and convenient for potential new salsa dancers as well as less intimidating and provide a great stepping stone for those that eventually want to come to the more established nights.
Basically the encouragement of new nights and classes and there promotion ulitmately benefits the entire salsa scene. If we want more great new dancers/teachers and salsa nights for everyone.
Competition is a healthy thing... and gives the consumer choice,... also just like in any free market only the fittest will survive, faced with more choice, salsa students are more likely to find those teachers they like and who know what they are doing... and those teachers who know they are more than capable will always last and have nothing to worry about.
I don’t think anyone wants to tell you how to run your site Hugh... am sure you have a proper job and time constraints etc... but perhaps its time to re-vamp and upgrade the site to cope with the changes in the Cardiff salsa scene over the last few years, and enable it to keep up with the salsa sites of other areas where they are able to handle the increased listings thus benefiting there salsa scene whilst we are still left a little behind the times...
Just a suggestion... :-)
