Hi. I am in a similar position to you, back about 8 weeks after a 4 year hiatus. I am in a very small clan, just a few friends. We all have 10+ game experience but have been off and on during that time.
Mostly we chat together, some light bossing but nothing at the Solak level etc. You are welcome to guest into our cc "Rise with Honour" and check us out. Alternatively you can add me in game. I have added you in case you would like to message me.
Good luck with your return to RS
