First of all, have a look at the FAQ (Frequently Asked Questions) section to see if your query is answered there. If not then browse the User Manuals / Wiki area which contains many details of how to use the simulations. Perhaps your question has been asked on the Forum?

A list of "who does what" can be found here

Finally, if all else fails, then please use the Administration Contact page to get in touch with one of us. Please note that we cannot answer general simulation or timetable questions as these are far better discussed on the forum where you are likely to get a far quicker answer anyway.
