Having a look at the mtb races this year to sign up for, having checked the following website, are there any that I might have missed or should have a second look at? Keen on just enjoyable MTB races, like the STBB (holding thumbs they coming back this year), Grabouw MTB, Nissan Trailseeker (wellington), Tiletoria, etc. - https://www.stillwatersports.com/event/ - https://www.pedalpower.org.za/events/ - https://www.dirtopia.co.za/index.php/mtbcalendar - https://www.entryninja.com/events/event - There seems to be good news about some that is coming back for 2019, and some that just seem to have gone missing, and some that have changes in format (ie Grabouw weekend warrior) Who knows of races that might be also worth a look at (already signed up for the Autumn Splendour MTB and considering the Pioneer School race in Worcester).
