Even this challenging situation would ease
I think you are asking about joining the ISC content development team of writers who are working on the content for various sections (presently it is the Courses database.) Members are selected for this work based on the quality of their contributions in various sections, keeping in mind English and writing skills as well as adherence to rules of the site. From time to time editors who see potential recommend names of members for the work or a formal announcement may be made as per the requirement. So let your work speak for itself. Your membership level as such will not matter.
Keep smiling...one day life will get tired of upsetting you.
