Heya,
If i'm reading your post correctly then i'm sorry to say that most, if not all, of those people will have been lying. To the best of my recollection we only have 2 former coders, one of whom doesn't do custom/vbulletin work anymore (Deceptor) and David, who was let go as he was unable to commit the time required to create and support products up to our standard.
Generally if someone is claiming to have worked with us, it'd be a good idea to check - a lot of people will no doubt lie to try to get work off of the back of our name and it sounds like you may have been misled and could have benefited from doing some basic background checking.
Regarding the slider - the majority of the feedback on it has been positive, and we go out of our way to ensure people know what they are buying. As well as offering a Lite demo version we also have a pre-sales questions forum with an average response time of a couple of hours. In addition we even have portions of the terms and conditions set aside to covering instances such as this:
We do everything we can think of that is possible to ensure people are not misled and are able to find out/ask about a products feature prior to putting their money down on it, but we know we're not perfect and there may be things we could be doing that we aren't, so we are always on the lookout for good suggestions on how to improve.
It's generally not a good idea to just assume *any* product will do exactly what you want it to - different people have different idea of what is an essential or necessary feature.
If there's anything else you think we should be doing beyond offering a Lite version with 70%+ of the features included, having sections of our Terms & Conditions telling people it is their responsibility to make sure the product does everything they want *before* they buy, having a box indicating the customer has tried the Lite version out and having a well-monitored pre-sales forum in order to help customers or potential customers we would appreciate the feedback.
Just wanted to pop in and thank you for your feedback and give you the heads up on those coders really - i'll leave you in Brad's capable hands when it comes to what is/isn't possible or planned for the slider
