The platform is very robust but still easy enough for beginners who don't have years experience under their belts! Sometimes it's difficult when there aren't many resources available online that talk about how best implement this or which plugins work well within our system (we're not looking at third party solutions).
We've had some issues where we'd run outta memory during peak usage periods - so whilst I can see why they would suggest upgrading if possible as an option; sometimes its better just getting things done first time around! It was something completely different again once i got used too though :) We were able to create reports easily without having previous knowledge/experience - plus get feedback straight away on what works / doesn’t etc.,.
