Thanks for the reply.
Yes I am looking for “contribution welcome” or “good first issue” labels and I already have contributed to one small suggestion but for the others the framework is too complex for me to make any meaningful contribution.In this case I will need some one to guide me.
Also I have been to several SIGs meetings but it looks like that I have to expose my desire to contribute more  . For helping the other I do this form time to time but I guess I will have to do this more often
