There is absolutely no need for explanations from anyone except me; if there`s anyone to blame regarding lack of involvement, it is I. Reasons are various, clichéd and pointless to enumerate.It's a pity this has happened.
I regret that my lack of involvement has contributed to Sol-Ek-Sa's end. I've no explanation to give other than once my classes started, I simply did not dispose of the amount of time to give requests the attention I felt they deserved.
Perhaps once I've finished my courses I'll attempt to join the successor to SES.
However, I strongly believe there is also no need to mourn the loss of SES, for I am sure the new incarnation will prove to be a much better resource.
