Shorter posts might work. And try using shorter sentences in general, although you said you find that difficult. I would definitely say one thread at a time might be a good place to start, especially for non-combat ones.

I'll be very happy to work with you on a thread or help on your threads to look at where you can maybe break up sentences more. That can definitely be done with counting the amount of clauses. Maybe restricting them as Nev says to two or three a sentences?
