The Signal Box Forum has been temporarily taken out of service for two reasons:

  1. The need to apply a complicated technical upgrade to bring it up to the latest level of security
  2. The need to implement the new data protection laws which are already in force.

I am sure most forum members will know that this site is run on a purely personal/hobby basis and my personal circumstances do not currently give me the time to carry out this work as quickly as I would have liked to have done.

For this reason, the forum will remain off-line for an undefinable period. Please check back here from time to time for updates.

The current status is that it has been established that there is an identified bug in the supplied upgrade when upgrading from the specific version we are using, but the developers have discontinued support on the matter. It is possible that we can upgrade in a two-stage exercise - to an intermediate version and then to the latest - but this represents a lot of work and will need two clear days minimum. I do have other ideas that might work if that does not.

As said above the key issue is lack of time owing to personal matters.

Please do not email me asking for more information, everything there is to tell is given here.
