Question Author
No Berti the author's question made no reference to MI5. The purpose for permanent deletion of the thread is to erase all existence of it having existed thus no allusion should raise the non-existence of a subject denied its very existence in the first place. All curiosity appeased *~)
Mibn - Your aspiration to attain the 'calibre of excellence' you eloquently describe is most commendable, admirable, praise-worthy and if I dare say, somewhat preys upon my sympathy, especially in your assertion that there are 'those who might be better off without an endorsement from me.'
A person, such as I interpret you to be, who is interesting, understanding, encouraging and self-conscious, not only serves a worthwhile purpose simply by the fact of their existence but their attractive modesty suggests that their potential abilities are far greater than they recognise or acknowledge of themselves. That is the only limitation I see.
