you are doing very well Samm...quietly finding out how things work...the options available to posters are very sophisticated and user friendly...it takes a bit of getting used to , but after a week or two , you will find your posting experience is very enjoyable...and your options are plentiful
being able to post and once it's up , to be able to correct things , or alter layout or whatever , is one good feature...as is the preview function...have a try and a play with all those features so you are familiar with them...YOU can also delete YOUR OWN posts , so don't be afraid to try things...if it doesn't work...delete it
