Should someone want to be and to ask to be shliach tzibur or should this be reserved for someone with yiras shamayim (fear of heaven) and if one does not feel he has this then allow someone else to lead?
Additional detail: -Either everyone or almost everyone has the ability to say the words of the prayers, knows the proper sequence of the prayers, minhagim unique to the shul's nusach, and if applicable minhagim unique to that shul. -edit from chazan to shliach tzibir to show this isn't a question about making parnasa
