In reply to jim: Sorry, long post alert!
In addition to buying/reading manuals and going on training courses, nothing wrong with that, just keep seconding as much as possible on single pitch trad. If you are doing plenty of seconding involving gear removal, especially on well protected steeper and hard-er routes (HS-HVS), then you should be picking up trad skills and be starting leading. If you can second any route cleanly, then with some basic trad skills you stand a good chance of leading it. IMO, seconding then leading can sometimes give a better feeling of achievement than just on-siting. And it may be safer if doing grades nearer your limit.
And this might be stating the obvious, but as a beginner stick to leading well protected routes (and learn to spot them at the crag) and don´t underestimate being an attentive, serious belayer (I´m not assuming you aren´t already!). It helps find experienced trad climber partners to learn from, particularyly the experienced older variety, if you always come across as a committed belayer
. Obviously once again, you may have some already.
